通过学习LDPC编译码原理，编写了LDPC码的编译码程序。通过此程序可以更好的实现LDPC码的仿真(in this passage we have write the program of edcoded and decoded of LDPC code.through it we can undersatand LDPC more.)

说明：  这是2自由度并联机构的位置反解和一阶影响系数求输入速度的代码(This is a 2-DOF parallel mechanism of the inverse position and the first coefficient of seeking input speed of the code)

表面肌电信号emg的处理程序，使用matlab编写(emg signal processing)

OFDM系统通过在时域符号前插入大于信道冲击响应长度的循环前缀（CP）可以避免符号间干扰(ISI)和载波间干扰(ICI)。但是，过长CP会使得数据传输效率降低。可以采用最小均方误差（MMSE）信道缩短均衡技术来压缩信道冲击响应长度。(OFDM systems avoid inter-symbol interference (ISI) and inter-carrier interference (ICI) by inserting a cyclic prefix (CP) larger than the channel impulse response length before the time-domain symbol. However, long CP will reduce the efficiency of data transmission. A minimum mean square error (MMSE) channel shortening equalization technique may be employed to compress the channel impulse response length.)
